We have studied properties of a nonlinear one-dimensional model for motion of the basilar membrane. The model is able to reproduce a variety of physiological and psychophysical effects, and in some instances predictions of the model have been subssequently confirmed. We regard the agreement between model and nature as evidence that the major features of the model are qualitatively correct. Areas of agreement include generation and propagation of two-toine distortion products, two-tone suppression, and Zwicker's psychophysical masking period patterns. In order to reproduce all of the above effects, the model must contain the following major features: (1) A mechanical nonlinearity. This nonlinearity is asymmetric, with membrane damping increasing during the same phase of membrane motion that elicits response activity in primary auditory fibers. (2) An additional stage of sharpening, a 'second filter', between the physical variable controlling mechanical nonlinearity and the physical variable controlling neural excitation.
我们研究了基底膜运动的非线性一维模型的特性。该模型能够重现多种生理和心理物理效应，并且在某些情况下，模型的预测随后得到了证实。我们将模型与实际情况的相符视为该模型主要特征在定性上正确的证据。相符的方面包括二倍频失真产物的产生与传播、双音抑制以及齐克勒的心理物理掩蔽周期模式。为了重现上述所有效应，该模型必须具备以下主要特征：（1）机械非线性。这种非线性是不对称的，在引起初级听觉纤维反应活动的膜运动的同一相位期间，膜阻尼会增加。（2）在控制机械非线性的物理变量和控制神经兴奋的物理变量之间有一个额外的锐化阶段，即“第二滤波器”。
